Try Harp maybe, I don't think that's GMO.

Most large volume North American beers are going to be corn based and therefore likely GMO.

Personally I just don't like the taste (lack of) of most high volume beers. If I don't have a huge selection I'll try and get Stella or Kronenberg. For mid-sized breweries I like a lot of the stuff from Phillips, Big Rock and Central City.

Kilkenny, Guiness, Tetley, Newcastle Brown are probably my top ones, I never get tired of those.

For cheapy/lighter stuff I'll usually have Rolling Rock, Red Stripe, Stella, Kronenburg, Heineken, Harp.

Personally what I always do is buy one beer I know I like and then one I've never tried, founds lots of good ones that way.

I tried a Corona for the first time in ages the other day, it was basically just air and bubbles.
